SANTA FE, Texas (FOX 26) - Her family searched frantically for 16-year-old Shana Fisher, only to learn she was one of 10 people killed during Friday's shooting at Santa Fe High School.

Less than three days after losing Shana, her great grandmother, Peggy Wainwright, was very emotional as she tries to cope with the "senseless violence" that took Shana's life.

"She was my granddaughter. She's part of the family and she was very much loved. This is just senseless-- senseless loss. That's all I can say," Wainwright said.

"She was just sweet. I remember the times when she would come up to me and say, 'hey granny,' and I'd give her a hug and kiss from me."

For hours, Wainwright said several family members were at the high school, Alamo Gym and various hospitals, looking for the nearly 25 extended family members that attend Santa Fe. Within a few hours, all were accounted for, except Shana.

"We were hoping that she ran out of the building and hid in the woods or something. My granddaughter Jenni called all the hospitals looking for her and we couldn't find her. And as the day went on, we just knew in the pit of our stomachs that it wasn't good, that she was gone," Wainwright said.

"I was like, 'what do you mean you can't find Shana?' Nobody's seen her, nobody's heard from her and she's not answering her phone. She was the type that if she wasn't near her phone, she would call to let you know that she was ok," said Anna Wainwright, Shana's great aunt.

It wasn't until nearly 4 or 5 in the afternoon, when Anna found one of Shana's classmates who confirmed their worst fears.

"I was at Alamo Gym and all the students that were in the classroom had been bussed over. So I was like, 'does anybody know Shana? Does anybody know Shana Fisher?' And this one kid who was in that class that morning was like, 'yeah, I do.' And I was like, 'you need to tell me.' And he told me yes, she did get shot, but didn't say where or how bad it was," Anna said.

It was her family's worst nightmare. Wainwright said there's only one thing to do moving forward.

"Get them involved in family stuff. Check what your child's doing in his room or where your child's at. Give them ground rules, teach them morals," Wainwright said.

Family members also tell FOX 26 it's unclear whether Shana knew her suspected shooter, Dimitrios Pagourtzis, or how the two were connected.

Currently, her family is waiting to retrieve Shana's body from investigators following an autopsy.
